Elevation creates graduation and layers and is usually described in which metric?

Elevation in haircutting refers to the angle at which hair is held away from the head while it is being cut. This process is essential for creating different styles such as graduation and layers. The measurement of this angle is typically expressed in degrees. By altering the degree of elevation, a stylist can control the amount of weight and texture in the hair, resulting in varied hairstyles.

For instance, a 90-degree elevation is often used to create uniform layers, while a lower elevation might be employed for creating graduation that blends lengths. Therefore, understanding elevation in degrees is crucial for hairstylists to achieve their desired effects and looks in various haircuts. Other terms like lines, metrics, and sections do not accurately represent the precise measurement of the angle at which hair is cut, making the use of degrees the most appropriate choice.
